everybody knows that there is serious problem of water pollution on the earth. yes, water pollution is increasing.
look! the water in the river is getting dirtier and dirtier. most of fish in the water have died, and we cant swim in the water.
my grandfather says, when he was very little, the water in the river was very clean. he often swam in the river with his friends.
that was before, but now we cant see such clean rivers. lets protect the water from pollution, because we cant live without water. the water is really important to us all.
大家都知道，在水污染严重的问题。是的，水污染加剧。
看！河水变得越来越脏。水里的游鱼大部分已经死了，我们不能在水里游泳。
我的祖父说，当他很小的时候，河里的水很干净。他经常和朋友一起在河里游泳。
那是以前，但现在我们不可能看到这样清澈的河流。让我们保护水不受污染，因为没有水我们就不能生存。水对我们很重要的一切。
